Master-Master Replication With MySQL 5 On Fedora 8
Author: o.meyer • Tags: fedora, high-availability, mysql • Comments: 3Master-Master Replication With MySQL 5 On Fedora 8 This document describes how to set up master-master replication with MySQL 5 on Fedora 8. Since version 5, MySQL comes with built-in support for master-master replication, solving the problem that can happen with self-generated keys. In former MySQL versions, the problem with master-master replication was that conflicts arose immediately if node A and node B both inserted an auto-incrementing key on the same table. The advantages of master-master replication over the traditional master-slave replication are that you don't have to modify your applications to make write accesses only to the master, and that it is easier to provide high-availability because if the master fails, you still have the other master.

Server Monitoring With munin And monit On Mandriva 2008.0

Tags: mandriva, monitoring •
Comments: 0 Server Monitoring With munin And monit On Mandriva 2008.0 In this article I will describe how you can monitor your Mandriva 2008.0 server with munin and monit. munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration, whereas monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected. The combination of the two gives you full monitoring: graphics that lets you recognize current or upcoming problems (like "We need a bigger server soon, our load average is increasing rapidly."), and a watchdog that ensures the availability of the monitored services.

Connecting GPRS From Ubuntu Gutsy
Author: saturn • Tags: ubuntu • Comments: 1Connecting GPRS From Ubuntu Gutsy Connecting to GPRS using a Nokia Phone is not too tough in Ubuntu Gutsy. This is because the default udev rules does install the required drivers and map most of the Nokia devices to /dev/ttyACM0. But it can become tough if you need to retain the resolv.conf or making the pppd to add a default route to the connected device. We will see how it was done properly in the Saturn Labs.

Meet the Anti-Nmap: PSAD (EnGarde Secure Linux)
Author: secureguardian • Tags: security • Comments: 0Meet the Anti-Nmap: PSAD (EnGarde Secure Linux) Having a great defense involves proper detection and recognition of an attack. In our security world we have great IDS tools to properly recognize when we are being attacked as well as firewalls to prevent such attacks from happening. However, certain attacks are not blindly thrown at you - a good attacker knows that a certain amount of reconnaissance and knowledge about your defenses greatly increases the chances of a successful attack. How would you know if someone is scanning your defenses? Is there any way to properly respond to such scans? You bet there is...

Zabbix 1.4.4 From Source On Debian Etch
